I don't recall the pressures when I charged the system back in may, the vent temps get to around 40 degrees on high fan speed and in the mid to upper thirties at a lower fan speed when ambient temps are in the 90s or below. In lets say 110 degree weather, vent temps are around 50 degrees high fan speed and lower 40s at a slower speed. I agree with you larry about the sanden compressor. I have been very pleased with it. Another thing I noticed is that vent temps at the outer two vents are not as cold as the center vents. Do you think this to is caused by outside air geting into the system?
